The girl that appeared in the fashion magazine resembles Satsuki due to her appearance, except, she has blonde hair while Satsuki has brown hair.

Satsuki with blonde hair?

Also, the "Big Bridge" magazine haves gilr that looks like Mois in her gorgeous style from 247a. The reason is different because the woman doesn't have wristband on her right hand like Mois does, she also has different color skin, hair and no lipstisk on it at all.

Mois' doppelganger?

Omiyo and Melody Honey made cameos in this episode as silhouettes.

The method of using make-up to invade was already improved in episode 247a where the Keroro Platoon was using it for the invasion with Mois' help while still on lipstick.

When Keroro is saying that Pekoponian women are still attracted to make-up, Keroro's animation is ugly because his hat's ears are covering his face a little and he doesn't have a chin when he is opening the mouth. However, this error was corrected and reanimated with the better animation.

After Keroro uses some make-up accessory to dress up into three women with the bad result, their animation is wrongly animated and without the lipsticks. However, these errors were corrected and reanimated on DVD version.

The first woman with the violet dress has wrong colored eyes, they are briefly colored blue, while the rest are still green. And her eyelashes are too thin and only 2 on each one eye.

The second woman that is wearing a beige shirt, doesn't have hair on her forehead. Her eyes are green (they should be colored, but they are not.), they are open, her eyelashes are too thin just like the first woman, with 5 of them in one eye, and her boobs are a bit small.

The last one when she is crying that she used the wrong eyeshadow, her eyes don't have any tears at all.

After Keroro tells Dororo that women think men are3 annoying, Dororo's Trauma mode is on, his position is different, and his eyes are open. But this error was fixed and reanimated on DVD version.

When Keroro is telling everyone about his fearsome make-up plan, his mouth is a bit different than usual. However, this error was corrected and reanimated on DVD release.

When Natsumi is wiping off the messed up lipstick while it can't be wipe out, her messed up make-up disappeared for a few frames.

When Keroro and the others are doing the resonance, the background is purple-white and the katakana words are not colored because it was reused for the other episodes. In this episode, this error was corrected on DVD release.

When Dororo's Trauma is still on while Keroro and the others are still resonating, the kanji word chuu is missing. But this error was fixed on DVD.

In the preview, Kururu's right spiral on his glasses has been switched to left for some reason.
